firewire: core: optimize card shutdown
This fixes a regression by "firewire: keep highlevel drivers attached
during brief connection loss": There were 2 seconds unnecessary waiting
added to the shutdown procedure of each controller.
We use card->link as status flag to signal the device handler that there
is no use to wait for a come-back.
